Important: The Leader account should be "off" in Copilink.

Correct setup:
1. Select your Leader account from the "Leader Account" dropdown in Copilink
2. The Leader should show a yellow underline in the accounts list
3. Keep the "Market" toggle OFF on the Leader
4. Your Leader trades normally in NinjaTrader

How it works:
- Leader executes trades through NinjaTrader's native connection
- Copilink detects those trades and copies them to followers
- Leader does NOT need to be "connected" in Copilink

Common mistake: Turning "Market" toggle ON for the Leader (this is wrong!)
